• It is very important to read and comply with the information on the switching charac-

• It is advisable to configure at least one relay output as a fault output and define the out-
puts' response to error.
• The relay output is configured as a normally open (NO or make) contact by default. It
can be reconfigured as a normally closed (NC or break) contact by means of a jumper
on the relay module ( please refer to the Operating Instructions Proline t-mass 65,
BA111D/06/en).

group is this function ASSIGN RELAY

value can be greater or less than the switch-off point. Negative values are only permitted
